I have used a ferris 61" walk behind for years with the grass gobbler and extension. It will fill up quick with un chopped leaves but you just have to chop them up with some gator blades a few times then suck up the remains. Works REAL good at an easy budget. The stander won't be as good on hills as well as bumping over rocks an things. Also the ferris walk behind is completely bullet proof!!! I ve had many of them and know!
